Searching for 1room flats in Jena, near Uni

Hello, I need a 1 room flat in Jena as a freshman of Uni. I will arrive on around 1st Oct. I 'd like to pay 300 euro per month for maximum as final price.

My private informantion:
1, I am female, clean things a lot,and usually keep everything tidy.
2, Outgoing, and love to make friends.
3, Not expert in German, but English is ok. Don't worry, I am studying it hard.

Hereare some my requests:
1, Furnished room. Simple decoration is fine, and some basic furnitures are essential, such as the desk, bed, closet, telephone and wifi.
2, It would be great if there are separated bathrooms and kithchen, but it's ok if not.
3,Quiet environment and atmosphere. I will need proper place to study for my Master degree.
4,Flats near the University is the best. Hopefully！
5,I don't have pets!

Finally, I really need to find a place to leave within a month, and I am trapped in China because of the Visa processing period. And I will coordinate with everything patiently.
Please don't hesitate to contact with me if you have a proper flat to rent. Sincerely!
